Summary

  • Add a task-oriented guide for managing ADC configuration through CI/CD, covering ownership scopes, label selectors, protected credentials, plan artifacts, serialized non-atomic deploys, drift detection, and rollback.
  • Document the pinned api7/adc container helper, including why the image entrypoint must be overridden, why the host user cannot be substituted, and that uid 65532 must be able to write diff.yaml.
  • Correct adc validate availability: API7 Enterprise 3.9.10+, Apache APISIX only when /apisix/admin/configs/validate exists.
  • State that ADC has no apply-plan command, that adc diff exits 0 when it finds differences, and that dumped files can include unscoped empty global_rules and plugin_metadata maps.
  • Replace the workflow page's copy-pasteable lint && validate && diff && sync block with a pointer to the production model, and order the docs index as workflow → resource IDs → label selector → CI/CD.

Why

The existing workflow documentation explained individual commands but not a safe production delivery process. Operators need explicit guidance about destructive synchronization scope, credential exposure, plan/deploy consistency, concurrent jobs, partial failure, and recovery.

Local verification against ADC 0.29.0 and Apache APISIX 3.13 also showed that treating validate and a post-sync empty diff.yaml as universal steps is incorrect for many APISIX versions.

User impact

Readers now have one end-to-end operational model:

  1. lint every proposed change without credentials
  2. validate trusted changes when the backend supports it
  3. preserve and review diff.yaml without applying that file
  4. recalculate the plan immediately before an approved deployment
  5. serialize deployments to the same ownership scope
  6. detect drift only after a stable empty diff
  7. roll back from version-controlled configuration without syncing unscoped dump keys

The guide supports both Apache APISIX and API7 Enterprise while retaining the warning that the APISIX backend is experimental and often normalizes defaults such as route priority and upstream hash_on.

Validation

  • Inspected ADC 0.29.0 CLI, Docker image (WORKDIR=/home/nonroot, uid 65532, /home/nonroot mode 0700), label injection, non-atomic sync, and diff.yaml writer
  • Ran Prettier-equivalent whitespace check (git diff --check) and verified relative documentation links
  • Ran the documented lint, diff, sync, label-selector isolation, rollback, dump, and ping flow with api7/adc:0.29.0 against disposable Apache APISIX 3.13.0
  • Confirmed adc validate fails on APISIX 3.13.0 (missing /apisix/admin/configs/validate) and that a minimal service/route does not round-trip to diff.yaml: [] because APISIX fills defaults
  • Did not re-run a licensed API7 Enterprise backend in this pass

Merge Risk: 🟠 High · up to 4b415

The guide currently risks exposing private keys or secret-bearing deployment artifacts, accepting stale drift results, and deleting gateway-wide resources through unscoped configuration maps. These issues should be corrected before merge because they could cause security incidents or destructive deployments.

Full details: E2e Test Quality Review

Explanation

Blocking error-handling issue in the new drift-check example. The added shell block runs adc diff without checking its exit status before reading diff.yaml. The CLI exits 1 when its tasks fail (apps/cli/src/command/diff.command.ts:102-105), but a shell without errexit can continue. If an older diff.yaml contains [], the block then exits 0 and reports no drift despite the failed backend operation. This failure path was introduced by docs/guides/ci-cd.md and is not covered by the described E2E validation.

Resolution

Update the drift-check block to handle adc diff failure explicitly, for example: if ! adc diff -f gateway/adc.yaml --label-selector team=catalog,env=production; then echo "adc diff failed; cannot determine drift." >&2; exit 1; fi, then perform the diff.yaml content check. Do not rely on a CI provider's implicit errexit setting.

Full details: Security Check

Explanation

Category 1 — CRITICAL — finding at docs/guides/ci-cd.md:106 (repeated at lines 197 and 225). The new guide instructs operators to upload the complete diff.yaml as a CI artifact, but the plan contains unredacted resource values. rust/crates/adc-cli/src/main.rs:132-134 serializes every Event directly. Events carry raw new_value and old_value (rust/crates/adc-sdk/src/event.rs:28-40), and the differ places local and remote values into those fields (rust/crates/adc-differ/src/differ_v4.rs:154-182, 287-288). These values can contain arbitrary plugin configuration, consumer API keys, and TLS private keys. The new documentation therefore activates an existing serializer and exposes secrets through CI artifacts without a redaction or artifact-access warning. The guide correctly treats dumps as sensitive, but it does not apply that warning to diff.yaml. Category 2 — No issues found. The pull request changes documentation only and adds no database persistence. Category 3 — No issues found. It adds no mutating endpoints or permission checks. Category 4 — No issues found. It adds no resource-access implementation; the guide documents ownership scope limits. Category 5 — No issues found. The guide explicitly prohibits ADC_TLS_SKIP_VERIFY in production and adds no TLS implementation. Category 6 — No issues found. The guide warns that selectors do not scope global_rules or plugin_metadata and warns against syncing unowned dump keys. Category 7 — No issues found. The changed documentation does not introduce unresolved $env:// or $secret:// references.

Resolution

Do not recommend uploading raw diff.yaml to a normal CI artifact. Either remove the upload instruction or require a protected, access-controlled, retention-limited artifact and explicitly label it as secret-bearing. Prefer adding a sanitized plan output that masks consumer credential configs, plugin secret fields, TLS private keys, upstream client keys, and other credential-bearing values before artifact serialization. Keep full values available only to the sync operation, and add regression tests that prove secrets never appear in the review artifact.

The previous CI example treated validate, empty diffs, and container
`--user` as always safe. Local ADC 0.29.0 runs against APISIX 3.13
showed those assumptions fail, so the guide now matches actual command
and image behavior before review.

ADC's own e2e suite gates validate at 3.17.0. Rechecking 3.18.0 showed
validate succeeding and a minimal service round-tripping to an empty
diff, so the CI guide should not treat 3.13 Admin API gaps as current
APISIX behavior.

Reuse the same `docker run` options for `validate`, `diff`, `sync`, and `dump`. Mount CA and mutual TLS files read-only when those files are not already in the repository:

```bash
-v "/path/to/gateway-ca.pem:/certs/gateway-ca.pem:ro" \
-e ADC_CA_CERT_FILE=/certs/gateway-ca.pem

Do not allow mTLS private keys in the repository.

The phrase “when those files are not already in the repository” includes ADC_TLS_CLIENT_KEY_FILE. A reader can interpret this as permission to commit the client key and point the container at the checkout. State that only non-secret CA material may be versioned. Always inject the client key from a protected secret and mount it read-only.

`validate` asks the backend to check the proposed resources without applying them. It requires API7 Enterprise 3.9.10 or later, or Apache APISIX 3.17 or later. On older APISIX versions the Admin API has no `/apisix/admin/configs/validate` endpoint and the command fails; skip `validate` then. `diff` prints a summary and writes the complete machine-readable plan to `diff.yaml`. Upload `diff.yaml` as a CI artifact so reviewers can inspect creates, updates, and deletions.

ADC has no apply-plan command. Reviewers inspect `diff.yaml`; they do not apply that file. `adc diff` also exits successfully when it finds differences. If a policy requires the job to fail on drift, inspect `diff.yaml` explicitly as shown in [Detect Drift](#detect-drift).

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Protect diff.yaml before uploading it as a CI artifact.

diff.yaml is a complete plan, not only an operation summary. It can contain oldValue and newValue for resources with consumer keys or other secret-bearing configuration. The ADC diff example includes a consumer key in these fields. (docs.api7.ai)

Do not recommend uploading the raw file without access and retention requirements. Require a protected, short-lived artifact, or redact secret-bearing fields before publication. Apply the same rule to the failure path at Line 197.

Also applies to: 197-197

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fail when adc diff fails before reading diff.yaml.

This script does not remove an existing diff.yaml or check the adc diff exit status. On a reused runner, a failed command can leave an older [] file, causing the drift job to pass incorrectly.

Add set -euo pipefail, remove the old file, and verify that the new file exists before comparing it.

+rm -f diff.yaml

Treat a dump as sensitive configuration. Store it in an access-controlled artifact location and define a retention policy. Dumped files can include empty `global_rules` and `plugin_metadata` maps. Those resources are not limited by `--label-selector`, so do not sync a dump back until you have removed keys you do not own.

Prevent empty unscoped maps from clearing gateway-wide resources.

global_rules and plugin_metadata are outside label-selector scope. If a dump contains {} for either section and the file is synced, ADC can interpret that as an empty desired set and delete all remote resources in that section. Removing entries from an empty map does not protect those resources.

Tell users to delete the entire top-level section, or exclude the resource type, unless the pipeline owns every resource in that section.
